Given numbers are 438,589,378,858,982
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,589,378,858,982 is 1141162480458.
Find LCM of 438,589,378,858,982 with Prime Factorization
| 2 | 438, 589, 378, 858, 982 |
| 3 | 219, 589, 189, 429, 491 |
| 73, 589, 63, 143, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 589 x 63 x 143 x 491 = 1141162480458
Therefore, the lowest common multiple of 438,589,378,858,982 is 1141162480458.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
438 x 589 x 378 x 858 x 982 = 82163698592976
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
438 : 1, 2, 3, 6, 73, 146, 219, 438
589 : 1, 19, 31, 589
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
982 : 1, 2, 491, 982
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,589,378,858,982, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
589:19x 31
378:2x 3x 3x 3x 7
858:2x 3x 11x 13
982:2x 491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3 = 72
Therefore, the value for common factors is 72.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 82163698592976/(1x72)
LCM = 82163698592976/72
LCM = 1141162480458
Thus, we can understand that the LCM of 438,589,378,858,982 is 1141162480458.
